Imaging findings of central nervous system neuroepithelial cysts.

Neuroepithelial cysts are rare and mostly asymptomatic cerebrospinal fluid (CSF)-like cysts. We describe herein the imaging findings in five patients with neuroepithelial cysts. Two cases of proven and three of presumed neuroepithelial cysts are presented.

[Pulmonary hemosiderosis. Hemodynamic or idiopathic origin? Diagnostic contribution of imaging and review of the literature].

We report two cases of Pulmonary Hemosiderosis. The first patient (adult male) had an angiosarcoma of the left auricle and developed pulmonary arterial hypertension, was treated by surgery and chemotherapy. The other patient (adult female) suffered from Idiopathic Pulmonary Hemosiderosis (IPH) and had been treated by corticosteroids for fifteen years, with one acute episode during this period.

[Radiologic aspect of benign pleural fibrous mesothelioma. Reports of 4 cases].

Solitary fibrous tumor or pleural fibroma is a rare tumor. It grows slowly and has a good prognosis after surgical resection. Pleural features, staging and even the fibrous nature are analysed by radiological findings.

[Gastric leiomyosarcoma. Contribution of imaging to the diagnosis. Report of 2 cases].

Leiomyosarcomas, are rare gastric tumors with a tendency for extraluminal growth. In relation to two new cases, the authors report the various features and show the predominant value of computed tomography for the diagnosis.
